I'm looking to build a kind of video wall. I have 4 LCD monitors which I've hooked up to a Mac pro to get a resolution of 3840x2104 on screen. Then I made an After Effects movie of a white box bouncing around the screen rendered at 3840x2104. What I'd like to be able to do is play the movie full screen and have it actually fill all four screens, but when I do Cmd+F and make it "full-screen", Quicktime is insistent on just filling one of my screens. I can expand the window (in non-full screen mode) to fill all four monitors, but then I have borders everwhere which I don't want (IE, the OS X menu bar and the "play" buttons at the bottom, etc). Quicktime has full screen settings which allow you to choose which monitor you'd like to fill, but (from what I can tell) there's no way to have it use more than one monitor. Does anyone know of a way I can play the movie across all four screens? I thought maybe another media player would offer this functionality, but I tried using VLC and it didn't seem to. Are there any other third party packages supporting H.264 that might offer this? Is there some plugin or method for Quicktime to beat it into submission?

QuickTime has started playing only 3 or 4 seconds of some avi movies. The timer bar goes all the way to the end, but only lasts a few seconds. The files play fine in VLC or on my WDTV, but not in Q.T. It seems very selective, sometimes it does it, then it will play just fine the next day. I have Perian installed. I have Tiger (10.4.11)

I have everything connected and working to display my MBP to my Sony Bravia HDTV. I am using the TV as a second display. When I choose full screen for my iTunes movie, it goes black. The iTunes movie plays in reduced screen. Does anyone have a solution how I can play full screen?

I want to record a Quicktime movie using iSight as the video input, external audio (guitar) via a Focusrite Saffire LE (1874) audio interface and internal audio (a backing track) from either iTunes, Logic 9 or MainStage 2 (I don't care which), so I can record myself playing and then send the video to another guitarist via Dropbox or similar.

Reviewed dozens of posts on various forums and found some great advice but still having major problems. Just installed SSD on my 12" 1.33 GHz ibook G4. Super cool at first - saw the unlocked resolutions and changed to 1920x1080. Then decided it would be interesting to see the 90* rotation view. BIG mistake. did not work- screen looked weird then went blank.

had to shut down and restart without external monitor connected in order to see anything but a blank, grey, blue, or weird screen. now I cannot even get the regular mirror setting to work- no external monitor viewing at all. 1) won't recognize external display unless I restart with it already connected. 2) even then, only shows blue screen (color of my desktop) but nothing else anywhere to be found. 3) with Screen Spanning Doctor enabled, still get weird looking screen - external display still appears rotated 90 degrees based on mouse pointer movements, but cannot see anything except gray hash. Tried disabling ScreenSpanningDoctor, deleting it from trash, resetting PRAM and NVRAM (unless they did not reset for some reason though I followed apple's instructions), and repaired disk permissions.

Still same situation. Would be thrilled to get original settings back. Then I would probably try SSD again but avoid the rotation feature which I assume my ibook is not compatible with. Please help. Thank you.

I just bought a new monitor to use as a secondary display with my MBP. I'm trying to watch a video in Firefox on my secondary display, when I try to watch the video in full screen and move back the mouse on my MBP display and click on that display. The video on my secondary display will exit full screen. How do I stop this from happening?

I consider this an oddity in Lion. I have two monitors. If I have Mail open in the left one and let's say Address book on the right one, and I put Mail into full screen mode, the other monitor goes gray. So no way to have one monitor in full screen mode and still use the second monitor!

It's a Dell 29" monitor (I don't have the product name). I connected the two monitors using a mini-displayport-to-DVI connector. I would have chosen for HDMI, but the Dell monitor lacked that unfortunately. I've installed Windows 7 on a BootCamp partition, and I happened to be in Windows when I did this. When I turned it on, it was a duplicate display of my iMac screen. Same resolution. I went to control panel and screen resolution, and chose for 'extend these displays', but suddenly the resolution on the Dell went from 2560 x 1440 (like the iMac) to a max of 1280 x 800

I have Macpro 8 core, 2.8ghz/ati2600xt/6gb ram/640gb and when I play a MKV movie files in full screen (2560*1600 ON 30 " Monitor) I see movie in frames. I try on vista x64 ultimate - VLC, mediaplayer clasic - frames. OSX - VLC, QuickTime, frames. When I see the movie only in window. All is Ok.

I would like to make a video with QuickTime X screen capture function. I use my MacBook 13,3" with an external monitor. The desktop is extended on the external monitor. If I try to capture the screen with QuickTime X, it records only the main screen (the LCD of my MacBook). Is it possible to capture the external monitor?

I am trying to down load some college lectures from the Annenberg media educational site. I have tried a coupe different ways, including as a movie file.

I have also discovered the fact that I then have the option to "Save as Quicktime movie" which provides a fine quality file for viewing -- except it is tiny, and I cannot seem to find "Enter Full Screen" or any other option.

It is frustrating because while doing this, at some point I did stumble on a fell screen option (or double, fit, etc.) which has seemingly disappeared. The QT file is called "Western_Tradition_35.asf (video/x-ms-wmv Object)". When there, the File dropdown gives me only a Zoom option which is no help for the picture.

I noticed that after upgrading to Lion quicktime player won't play movies full screen on my second display. Under Snow Leopard if the quicktime window was on the second display and you hit full screen it would fill the display is was on. Now the video slides to the main display and then goes full screen. There doesn't seem to be any way to change that behavior. There are no preferences.

The only work around is to move the menu bar in the display preferences to the second menu, so that the second monitor becomes the main one.

My girlfriend shot a short movie with my digital camera and she had it turned sideways, so you've got to turn your head to view it right. I need to rotate it 90 degrees counterclockwise. I've got quicktime pro 6.whatever (the newest). It's an mpeg if that matters.

I recently upgraded to Snow Leopard and I have the latest Quicktime Player as well. QP used to have the controls below the video, but now they're over top of it.

I can move them around, but I can't seem to move them off of the video. This is highly irritating because it means I'm missing part of the video any time I use any of the controls, or if I just bump the mouse.

Am I the only one who's bother by this? Is there any way to change it or to revert to an older version while still using Snow Leopard.

Okay, so I am here at work, and have spent the last 4-5 hours trying to resolve this issue, and cannot find any working solutions for it on the internet. We have .3gp recordings. All of a sudden, we started getting this error on some of our computers. Example: I want to play test.3gp; I try to open test.3gp in QuickTime, and I get an error that reads...

"Error -2002: A bad public movie atom was found in the movie:test.3gp" But when I go to play test2.3gp, it plays fine. This issue varies from computer to computer. I get this error on all three of my machines. 2 Windows 7 64bit, and 1 Windows 7 32bit. My colleague and boss can play test.3gp fine through QuickTime on their computers. One is Windows 7 64bit the other is 32bit.

Anyone know some causes of this and hopefully a way to solve it? I tried cleaning up registry errors, running as administrator, updating, reinstalling... Nothing is working.

After updating Quicktime to 7.2 it has gotten really slow when opening a movie, VLC on the other hand does this in an instant.

I can open Quicktime Player itself pretty fast, but when I want to open something, I get the beachball spinning for about 5-10 seconds, only then I can switch to the player and watch it.

This is really annoying.. I don't want to use VLC, because it is not that stable and I hate to use its FF feature. Is there something I can do about it? I tried downloading QT player from Apple and reinstalling.

I have a .wmv file and when I try to open it in quicktime it only plays half of it, but when I attempt to convert it to a different format like .avi, the quality gets reduced but it will play the entire thing.

I purchased a Mac Pro sometime back to use in my office but the person in the office next to me also frequently has use for a Mac Pro and since we can't purchase two Mac Pro's now we decided to set up a system with multiple monitors/keyboard/mouse. We ran a 2nd DVI Cable and a USB Hub over to the other office and use that for a second monitor hooked onto this Mac Pro plus a 2nd Keyboard and Mouse. Fortunately the distance was not too far and it worked out well.

we're having is trying to figure out how to do the Screen Mirroring/Spanning. The Mac Pro has two video cards. Video card 1 is the Nvidea 8800 GT and the 2nd card is an ATI 2600 XT. I have the main monitor in my office which is a 22" Samsung Widescreen hooked up as video 1 on the Nvidea card. The 2nd monitor which is an Acer 19" Widescreen monitor has been hooked up to both video 2 on the NVidea card and even video 1 on the ATI.

I've been using mac for several years but have never had to burn movies to a disc before. I know that on a PC it is quite simple to burn multiple downloaded movies onto the one disk but I cannot work out how to do it on a mac, as the disk space fills up. I've downloaded "Burn" and "Visualhub" but neither seem to be able to do it.

I was just wondering if the iMac G5's (the late 2005 models, last ones without isight i think) can support using a VGA/DVI monitor as a proper spanned second display with something like screen spanning doctor that works on the old iBooks, rather than just mirroring whatever is on the iMac display.

i bought a mini vga to vga for my emac and am about to buy a monitor and i hear the ppcs can only mirror. so i know about the screen spanning doctor and think im going to use that, does anyone have the most current ones link as i cant find it and it works with leopard.
